According to the existing design information of a sluice in Ruyuan, combined w
3、ith the hydrological and geological conditions in the Ruyuan area, according to the relevant specifications of the design of the sluice, the structural type of the sluice is designed and calculated. According to the corresponding water conservancy norms, combined with the actual situation of a river
4、 in the Ruyuan area to determine the sluice project in the weir type, sluice type, size, should meet the river flood season flood requirements. The type and size of the intake sluice in the sluice project are determined according to the irrigation requirements of the local irrigated area. Based on t
5、he overall engineering layout of the sluice project, the seepage is calculated, the discharge capacity and the water supply capacity of the sluice are checked, and the calculation and design of the energy dissipation project are carried out, and the chamber of the sluice is calculated stably. Accord
6、ing to the design calculation, the layout of the hub, according to the provisions of the norms and requirements of the drawing layout and structure drawings.
